indication of heavy bacterial growth and activity in lower portions of the well where less
oxygen is available. Tho high incidence of anaerobic growth can lead to severe blockage al
well as coli(urtm release from these areas of licavy biolilm accumulation. Ileere is also
putential for anacmbic growth in the gravel pack and nearby formation area around the well,
so any rehabilitative Procedure utilized should provide for cleaning of this area.
flag microscopic analyses showed the presence of two types of iron oxidizing bacteria,
C rtmothrix and Gallionolla. Thcsc organisms oxidize iron, resulting in heavy accumulation of
insoluble oxides well in excess of their biolilm production. Ilie iron accumulation is
commonly associated with bridging of screen slots and reduced well production.
RE -COMMENDATIONS;
OMMENl),1TIO1r1S:
Overall, the Well shows considerable potential for bio-fouling due to heavy growth of slime
forming and iron oxidizing bacteria, as well as ana;-Tobic organisms. Recent coliform positive
tesfing would most likely be nssociAtcd with the strong anaerobic growth present in the lower
uvoll. In order to best address the coliforni presence, a complete chemical rehabilitation would
be recommended over chlorination, as thorough removal of the .anaerobic biomass should
Provide a more long-tenn solution with the additional benefit of improving well production.
C'hlorinalion tends only to oXI'dize the, surface layers of the polysaccharide biolilm, further
complicating the removal of bacteria present_
While the sampling method did clot supply information regarding the gravel pack and aquifer
water, a thorough rclt.tbilitllive effort including appropriate chemical treatment and thorough
mechanical work should provide sufficient cleaning of this area. If rehabilitation of the well
%'-ill tx; Perlbrmed, a cleaning solution consisting of hydrochloric acid and a bio-dispersant
product, such As the QC-21 product by Layne, ,Nould be recommended.

On November 13, 2001, this legislative body approved and recommended
that Layne Christensen be awarded the bid to remove, disassemble, and
produce a video log for Well No. 11. Due to the increased
bacteriological problems encountered by Well No. 19, on January 29,
2002, the Community Services and Water Department requested that the
funds and the study granted for Well No. 11 be transferred to Well No.
19. Upon the completion of the study, it was determined that Well No.
19 is in need of rehabilitation and the entire pump unit be replaced.
In 2001, Layne Christensen rehabilitated Well No. 15 and performed an
excellent job.
This has been reviewed by the Community Services and Water Department.
Based on the experience and familiarity Layne Christensen has acquired
with the City's wells, it is hereby recommended that their services be
retained to perform the rehabilitation and pump replacement for Well
No. 19 at an approximate cost of $258,127.00.

Memo
To: Bruce Malkenhorst, City Administrator
Fran: Samuel Kevin Wilson, Director of Community Services and Water
Date: April 16, 2002
RE: Well 19 Rehabilitation
Due to the highly technical nature of well redevelopment, I strongly recommend hiring a
consulting firm to perform the rehabilitation of Well 19.
City records indicate that Well 19 was constructed in September of 1988. Since this time, it has
never experienced any significant mechanical problems, nor has it ever been removed for
preventative maintenance purposes. In addition to an exceptional reliability record, Well 19 has
been a consistent performer producing in excess of 1300 gallons per minute for over 13 years.
Well 19 began experiencing bacteriological problems in January of 2001. From January 2001
to November 2001, Well 19 has tested coliform positive more than twenty times. Since
November of 2001, Well 19 has been off-line due to the above -mentioned condition. In
attempting to alleviate this, the Water Department has flushed the well, dosed it with large
volumes of chlorine, and in November of 2001, had it chemically treated by an outside
contractor. None of these measures have alleviated the bacteriological conditions.
In January of 2002, Layne Christensen representative, Don Leith, recommended that three
samples be taken from Well 19 and sent to their lab located in Ottawa, Kansas for analysis.
These samples were taken at the following intervals: startup, 5-minutes, and 10-minutes. The
results of these tests indicate a considerable bacterial presence in all three samples. In order
to best address the coliform presence, a complete rehabilitation is recommended to provide a
long -tern solution to this condition. A detailed report by the lab has been attached for your
review.
• Page 1
In February of 2002, Layne Christensen was awarded the contract to remove, disassemble
inspect, and video log Well 19. Upon inspection by Layne Christensen, it was determined that
the entire pump unit was in need of replacement. With the completion of the pump inspection,
a video log was performed and confirmed the well was in need of rehabilitation.
Over the past month, staff has done extensive research into the rehabilitation process. It was
ultimately determined that very few drilling firms possess the technical knowledge to undertake
a full-scale rehabilitation project of this magnitude.
G: My D==eftVnemosYnemos\WebWM 19 ReFiebi E6w.dw
As you are aware, Layne Christensen rehabilitated Well 15 and appeared to do an excellent
job. It is highly recommended that the City use Layne to serve as both the consultant and
contractor on this project. Layne uses several patented techniques that other firms do not use.
In fact, because of these patents, many firms' hire Layne as a subcontractor to expedite
various rehabilitation related projects. Below, are just a few of Laynes accomplishments in the
field of well rehabilitation:
♦ Layne Christensen has pioneered and pursued many methods of rehabilitation including
chemical, Aqua Freed, Bore Blasting and mechanical means.
♦ Layne Christensen has its own technical support group in Layne Christensen
GeoSciences. Layne GeoSciences is made up of chemists, microbiologists, geologists,
hydrologists and hydrogeologists. This support group uses baseline information and past
data to evaluate the wells hydraulic condition. As you are well aware, changing hydraulic
conditions may cause lost capacity, water quality changes, taste and odor changes and
sand pumping.
♦ Layne Christensen's Fontana office has conducted in excess of 1,000 well rehabilitation's
over the past twelve years. As previously discussed, Layne uses many patented
rehabilitation techniques.
♦ Anoxic Block: Layne's Patented equipment and procedures are used in gaining negative
bacteriological samples with use of inert gases and seals.
♦ Aqua Feed: Controlled injection of liquid CO2, a paten ted process for which Layne
Christensen holds the license in Southern California.
♦ Bore -Blasting: A Layne patented process using vibration, gas and water jetting.
♦ Equipment Layne has designed its equipment especially for the rehabilitation wells. Large
mixing tanks mounted on 40-foot loboy trailers have been designed with irgection pumps,
chemical storage compartments, eyewash and shower installations for safety purposes.
♦ N.P.D.E.S: Layne has designed and built four trailers with mixing, monitoring and injection
capabirdies to neutralize all chemicals which may be utilized in well rehabilitation.
♦ Layne has been selected exclusively by many local and international consultants for the
sole source of their tried and true methods of well rehabilitation. In a recent discussion with
Bert Mason of California Water Service, Mr. Mason informed me that Layne Christensen is
used solely to rehabilitate their wells due to their expertise in the field of rehabilitation.
Attached you will find the names and addresses of several jurisdictions that have used
Layne Christensen to facilitate the rehabilitation of their production wells.
Consulting Costs:
Layne will analyze all data collected from Well 19 and supply the City with a complete
specification list for rehabilitation and additional recommendations for a fee of $110.00 per
hour. It is estimated that this work will require 24 man-hours to complete.
Total cost:
Rehabilitation Costs:
The following is an estimate of the associated costs for full well rehabilitation:
♦ Mobilize and demobilize:

♦ Move in chemical mixing tank set up and mix batches above ground. Install a dual swab
with a 10' spacing and inject the chemical between swabs. During the injection process,
swab the chemicals into perforations in a 10' maximum spacing.
$51,441.00
♦ After chemicals have been injected, Layne will install the bore blast and "shock" the
chemicals into perforations and gravel pack agitating the space behind the casing as
much as possible.
$33,500.00
♦ After the chemicals have had sufficient time to work, Layne will reinstall the dual air swab
and jet the water into a Baker Tank and treat it to N.P.0.E.S. standards.
♦ N.P.D.E.S.
$19,000.00
♦ Fumish, install and remove a test pump capable of producing 4500 GPM to redevelop the
well to maximum production including a deep suction pipe to maximize the redevelopment
process.
♦ Mobilize and demobilize a test engine to operate the test pump including fuel and an
operator estimating 40 hours.
$12,180.00
♦ Layne will lower the Ph. to 4 — 4.5 before they start the final chlorination process. The
water will be sampled through out the casing with a "thief bailer" to assure the Ph. is at the
desired level. After the Ph. adjustment, Layne will chlorinate to 2000 PPM or more.
$17,415.00
♦ Remove the chlorination solution using the airlift method. Discharge solution to be placed
into Baker tank. Solution shall be treated to N.P.D.E.S. standards.

In conclusion, although the costs associated with well rehabilitation are high, the City has little
choice. I think it is in the City's best interest to use a drilling firm with vast experience and
knowledge to rehabilitate Well 19. Why chance using a drilling firm that does not have a full
understanding of the rehabilitation process. This could cost the City additional money, and
worst yet, the City could be stuck with a well that produces little or no water. With the City's
water demand steadily increasing, it is imperative that Well 19 be rehabilitated to its maximum
production capacity. With that said, I would recommend that the City bypass the formal bidding
process and contract with Layne Christensen Company to consult and undertake the
rehabilitation and pump replacement processes.
Please advise when time permits.

moderate amount of crystals.
OBSERVATIONS AND INTERPRETATIONS:
Dtie to 1ho depth of the wall and rump setting, 111c above set of samples would appear to
represent conditions present in tho columta pipe, mid -well and lower well. Sampling most
likely duos not reflect conditions prosent in the gravel pack and nearby formation, as

Bacteriological analyses of the samples submitted from well 919 show a considerable bacterial
presence. The initial or startup A.TP count is excessive, indicaating heavy bacterial growth
within the casing. "There is a subsequent reduction in the AI'P counts on the 5 and 10 minute
samples', however, the counts icmiain sufficiently high to suggest considerable bacterial
activity in the mid nad lower portions of the well. The heterotrophic plate counts for the
starttip and 5-ininuto samples show excessive growth, indicating strong growth and activity
among the organisms present. 17zc 10-minute sample plate count shows a reduction to 50
colony forming units.
Rzwh sample showed identification of a pt'olninent aerobic, slime-fonninb organism, with
Acrolnolias specie detected in the start-up and 5-minute4 samples and Pseudomonas specie
detected in tlne 10-minute sample. As part of it large overall bacterial population these
orbanisins would inerea.w thy; propensity for biofilnn accumulation in the well system,
'17tc strong presence of anaerobic growth and sulfate reducing bacteria in each sample gives
indication of heavy bacterial growth and activity in lower portions of the well where less
oxygen is available. Tho, high incidence of anaerobic growth can Iead to severe blockage as
well as colilurm release from these areas of lieuvy biolilm accumulation, 'Ilnere is also
potential for anaerobic growth in the gravel pack and nearby fortnalion area around the well,
,o any rehabilitative Procedure utilized should provide for cleaning of this area.
The; microscopic analyses showed the presence of two type' of iron oxidizing bacteria,
("reli othrix and Gallionella. Thee organisms oxidize iron, resulting in heavy accumulation of
insoluble oxides well in excess of their biolilm production. Ilie iron accumulation is
colmnionly associated with bridging of screen slots and reduced well production.
Overall, the -well shows considerable potential for bio-fouling due to heavy growth of slime
tinning and iron oxidising bacIL-ria1, as well as anar.robie organisms. Recent coliform positive
testing would most likcly be associated with the strong anaerobic growth present in the lower
roll. In order to best address the eolifonn presence, a complete chemical reliabilitation would
bu rccotnnnunded over chlorination, as thorough removal of the anaerobic biomass should
provide a mom long-teri n solution with the additional benefit of improving well production.
Chlorination tends only to oxidize the surface layers of the polysaccharide biolilm, further
complicaling the removal of bacteria present_
While the s;impling method did not supply information regarding the gravel pack and aquifer
water, a thorough rehabilitative of fort including appropriate chemical treatment and thorough
Inochanical work should provide stlflicient cleanuig of this area, If rehabilitation of the well
Nvill be poribrmed, a 'fanning solution consisting of hydrochloric acid and a bio-dispersant
product, such as the QC:-21 product by I.ayno, ti�•ould be recommended.

Each sample; showed Wmlilieation of a prominent aerobic, slime -forming- organism, with
Acromonas specie detected in the start-up and 5-minutes samples and Pgaudomonas specie

RE: Well 19 - Transfer of Well 11 Funds
Date: January 29, 2002
The Water Department is seeking authorization to use funds currently allocated for the
removal and disassembly of Well Number 11 and use these funds to have Well 19
disassembled and inspected.
Well 19 has tested coliform positive more than twenty times since January of 2001. Since
November of 2001 the well has been off-line due to the above mentioned condition. In
attempting to alleviate this condition, the Water Department has flushed the well, dosed it with
large volumes of chlorine, and in November of 2001, had it chemically treated by an outside
contractor. None of these measures have alleviated the bacteriological conditions.
In January of 2002, Layne Christensen was contacted and met Water Department officials at
Well 19. Layne recommended that three samples be taken and sent to their tab located in
Ottawa, Kansas for analysis. These samples were taken at intervals of startup, 5-minutes, and
10-minutes. The results indicate a considerable bacterial presence in all three samples. In
order to best address the coliform presence, a complete rehabilitation is recommended to
provide a long-term solution to this condition. A detailed report by the lab has been provided for
your review.
Please advise when time permits.

Bacleriological analyses orthe samples submitted from well ##19 ,show a considarable bacterial
presence. The initial or shu lap t1.TP count is excessive, indicating heavy bacterial growth
within the casing. There is a subac:clu4-jit reduction in tl-te ATP eotmts on the 5 and 10 minute
samples; however, the counts remain sufficiently high to suggest considerable bacterial
activity in the mid nttd lower portions of the NvelI. The lncterotrophic plate counts for the
startup and 5-minuto samples show excessive growth, indicating strong growdi atul activity
among the organisms present. Ilia 10-mirnrie; sample plate count shows a reduction to 50
colony forming units,
l,;nch sample showed idontilieation of it prominent aerobic, slimc-forinin , organism, with
Acromonas specie detected in the start-up and 5-minutes samples and Pscudomona..s specie
detected in ttie 10-iniuute saatnplo. As part of a large overall bacterial population, these
organisms would inoroat:e tho propensity for biofilm accumulation in the well system,
'Tllc strong presence of anaerobic growth and sulfate reducing bacteria in each sample gives
indication of heavy bacterial growilt and aciivtity in lower portions of the well where less
oxygen is available. ' bo high incidence of anaerobic growth can lead to severe blockage as
well as colirkwin release from these areas of heavy biofilm accumulation. 'There is also
potential for ariacmbie growth in the gravel pack and nearby forrnaatios area around the wall,
so any rehabilitative Procedure utilized should provido for cleaninb of this area.
The; microscopic analyses showed tic prosenco of two types of iron oxidizing bacteria,
Cn'tmthrix and Gallionella. Thew organisms oxidize. iron, resulting in heavy accumulation of
insoluble: -oxides well in excess of their biofilm production. "I'lie iron accumulation is
commonly associated with bridging of screen slots and reduced well production.
1tEMMMi:NDATIONS:
Overall, Ilia well shows considerable potential for bio-fouling due to heavy growth of slime
firming and iron oxidizing bacteria, as well as anaerobic organisms. Recent coliform. positive
testing would most likely be associated with the strong anaerobic growth present in the lower
well. In order to best address the colifornn preso nce, a complete chemical rehabilitation would
be re,ommunded over chlorination, as thorough removal of the .anaerobic bicnnass should
provide a more: long -tents solution with the; additional benefit of improving well production.
Chlorination tends only to oxidize: the surfaea layers of the: polysaccharide biofilm, further
complicating the removal of bacteria present.
While, the. sampling method did not supply information regarding the gravel pack and aquifer
water, , thorough rcltrtlnilitative: effort including appropriate chctnical treatment and thorough
mechanical work should provide sitMcie:nt cleanhig of this area. If rehabilitation of the well
will be porlbrmed, a c-leaning solution consisting of hydrochloric acid and a bio-dispersant
product, such as the QC-21 pro duct by Layne, -would be recommended.

Without a churnicai prolilo of the; water it is difficult to properly estimate the concentmlion of
acid nacess* M so I would recornmend basing die volume on other rehabilitation projects
Layne pe,�rfortned in the local area. In most cases this would include the use of at least tan 8-
1004► concentration based on 1.5 timcs the standing well volume. Me to tho heavy bio
fouling, the QC-21 should be iltilized at a full 3% concentration.
The chemistry should be ntixod above ground and applied to th,` well following a rigorous
Brushing of the entire well with tliorough removal of debris. Af1cr placement of the chornical
solution downholo, the entire well should be thoroughly worked with a surge block. Emphasii
should bo placed can working portions of the well (including the sump if present) and the
scraullcd areas to address any annerobio growth inside ilia well and. gravel pack. Surging
should be performtul for at lonst 6-8 hours the first clay, then altar rifting overnight at a low
pII, surging Should 1>6 perfor►ned for an additional 6 hours tho following day prior to pomp
out. Thoroughly evacuate the well starting at the bottom and working upward as the Water
clt;:cn. Maintain ilia pH tit 3.0 or below during the entire cleaning procem and dispose of
pamp out according to regulatory, requirements.

RE: Well 11 Repair
The Water' Department recently received Requests for Quotations (RFQ) fnorn three pump
repair firms for work to be performed on our Well Number 11 at 4305 Santa Fe Avenue. The
Water Department requested quotations for the removal and disassembly of the pumping
equipment and video log only. A separate set of RFQ's will be submitted for the repair of the
Pump equipment once the extent of wear and the condition of the wellhead has been
determined.
Well 11 has tested positive for colifomr bacteria on several occasions over the past two years.
This is often an indication that the wellhead is in need of rehabilitation; however, this cannot be
confirmed until after a video log has performed and reviewed. In addition, accordng to City
records, the pump urrtit has never been pulled for inspection. Thlimell was drilled in May of
1952.
Bids were taken from Beytik Drilling ($6,780.00), Layne Christensen ($3,795.00), and Reed
Electric ($7,970.00). 'Layne Christensen carve in Wrest with a bid of $$3,795.00.1 therefore
recommend using Layne Christensen for the r empval and disassembly of Well 11. A copy of
the rived RFQ's have been included for your review
